摘要: 本文采用灵活的气固反应法，将超薄g-C3N4纳米层均匀组装在碳纳米纤维(CNFs)上，在室温下通过连续原子层吸附法原位生长BiOI纳米片，在CNFs上实现了g-C3N4/BiOI异质结构的组装和构筑。通过扫描电子显微镜和X射线衍射仪对合成样品的形貌及组成成分进行系统分析。利用模拟太阳光降解毒性Cr(VI)的水溶液对样品进行光催化活性分析。结果表明，CNFs/g-C3N4/BiOI复合纤维具有优异的光催化活性，在重金属废水处理等领域可能会有重要的应用价值。
Abstract: In this paper, an ultra-thing-C3N4 nanolayer is uniformly assembled on carbon nanofibers (CNFs) by a flexible gassolid reaction method. BiOI nanosheets are grown in situ by continuous atomic layer adsorption at room temperature, and g-C3N4/BiOI heterostructures are assembled and constructed on CNFs. The morphology and composition of the synthesized samples were systematically analyzed by scanning electron microscope and X-ray diffractometer. The photocatalytic activity of the samples was analyzed with an aqueous solution simulating the solar degradation toxicity of Cr(VI). The results show that CNFs/g-C3N4/BiOI composite fiber has excellent photocatalytic activity, and may have important application value in heavy metal wastewater treatment and other fields.
